2020届一轮复习人教版选修七Unit 3 Under the sea单元作业(21页word版含有答案解析)

Unit 3 Under the sea完形填空之利用语境解题方法指导做完形填空题时牢记上下文的关联和语境暗示对解题会很有帮助。

上下文是形成语境的基础,做题时要学会瞻前顾后,做到词不离句、句不离段、段不离文。

因为有时如果单独看空格,看似几个选项填入空格都没有错,句子也通顺,但结合全文内容来理解,就只有一个最佳答案。

像这篇完形填空的第1题,下文明显出现了treatment,还有第11题和第12题,这两题关联很大,是相辅相成的。

14题和上文的last swimmer相对应。

典例引领 (2016天津)The journey my daughter Cathy has had with her swimming is as long as it is beautiful.Cathy suffered some terrible 1 in her early childhood. After years of regular treatment, she 2 became healthy.Two years ago, while Cathy was watching the Olympics, a dream came into her sweet little head—to be a swimmer. Last summer, she wanted to 3 our local swim team.She practiced hard and finally 4 it. The team practice, 5 ,was a rough start. She coughed and choked and could hardly 6 her first few weeks. Hearing her coughing bitterly one night, I decided to 7 her from it all.But Cathy woke me up early next morning, wearing her swimsuit 8 to go!I told her she shouldn’t swim after a whole night’s coughing, but she refused to9 and insisted she go.From that day on,Cathy kept swimming and didn’t10 a single practice. She had a 11 intention within herself to be the best she could be. My ten-year-old was growing and changing right before my eyes, into this 12 human being with a passion and a mission. There were moments of 13 of course:often she would be the last swimmer in the race. It was difficult for Cathy to accept that she wasn’t a 14 —ever. But that didn’t stop her from trying.Then came the final awards ceremony at the end of the year. Cathy didn’t expect any award but was still there to 15 her friends and praise their accomplishments. As the ceremony was nearing the end, I suddenly heard the head coach 16 ,“The highest honor goes to Cathy!”Looking around, he continued,“Cathy has inspired us with her17 and enthusiasm. 18 skills and talents bring great success, the most valuable asset(财富)one can hold is the heart.”It was the greatest 19 of my daughter’s life.

[高考拆组训练] 阅读理解组块专练练速度限时30分钟Ⅰ.阅读理解 A The amount of fish caught worldwide is much larger than has been reported. And that could mean serious problems for the environment and nations that depend on fisheries 渔业. A new estimate shows that it is 32 million tons higher than countries have been reporting yearly. The same report notes that the world s fish catch has been declining since the late 1990s. Countries report their industrial catches to the United Nations Food and Agriculture Organization. But they do not report other kinds of fishing. This includes the catches of small commercial fisheries, which are called artisanal fisheries, and fishing for recreation andindividual food. Daniel Pauly at the University of British Columbia in Canada led the study. He noted that a huge amount of some catches is thrown away. “For example, shrimp trawlers 拖网渔船keep only the shrimp and the fish that they catch often eight to ten times as much as the shrimp gets thrown away.” Pauly told VOA that better estimates of the actual global catch will help ensure there will be enough fish in the future. “B ut our figures suggest that since 1996 a rapid decrease is happening. And if you project this forward you end up in a few decades having much less catch, literally no catch. So that is potentially dangerous.” Researchers also found ways the world s fisheries are changing. They found that fishing fleets of larger nations are catching fish in the waters of developing countries more and more. Pauly said he was surprised by the amount of fishing done by foreign fleets in competition with local fishers. “In West Africa, the figure that was most astonishing is the enormous role of foreign fishing of European and Asian vessels fishing legally or illegally and competing against local fishermen. On the other hand for the US, Australia and some developing countries, such as the Bahamas, what was apparent is the enormous contribution of recreational fisheries, which also never get reported to the FAO.” Researchers say inaccuratedata also harms the development and supervision 监管of effective policy and management measures. 语篇解读世界范围内捕鱼的数量比报告中的数量要多很多，而这些虚假报告对经济和环境都造成了不好的影响。
